Your steel engineers are excellent.
Your composite pipe deserves the same expertise.

GRE (glass-reinforced epoxy) is a filament-wound composite pipe combining continuous glass fibre with an epoxy resin matrix. Its corrosion immunity in seawater and brines, light weight and smooth bore make it the standard choice for seawater service, firewater ring mains, produced water and desalination plant piping — services where carbon steel corrodes and exotic alloys cost too much.

Broadly: GRE (epoxy) handles higher pressures and temperatures and dominates oil & gas and firewater; GRP (polyester/vinylester) is economical for large-diameter, lower-pressure water service; HDPE excels in buried, surge-tolerant and marine outfall applications. The right answer depends on pressure-temperature envelope, chemistry, surge regime, fire case and installed cost — which is exactly what an independent material selection study resolves.

Because the dominant failure locations are joints and installation damage, not the pipe wall: poorly made adhesive bonds, unqualified bonders, point loads from bad supports, impact damage during handling, and surge pressures the system was never checked for. This is why our services concentrate on joint qualification, build surveillance and surge review.

Often, yes. GRE pressure ratings are derived from long-term regression testing, which also provides the framework for remaining-life assessment. Combined with condition findings and operating history, many systems support a documented life-extension case — and localized damage can frequently be repaired to ASME PCC-2 / ISO 24817 rather than replaced.

Yes — by design. We complement manufacturers, EPCs and inspection houses rather than competing with them: they supply, build and measure; we provide the independent composite-specific engineering judgment that protects the owner's interest across all of them.
